Step-by-step explanation:
I believe those are decimals
1) (576*3/128) minutes
2) 81 men, 19 women. Total 100. 81/100 men. With 250 members, (250*81/100) men

A pyramid always have a number of slant triangles equal to the number of the sides of the base.
This means that a pyramid always have the number of face which is one more than the number of sides of the base.
Therefore, given that a pyramid has n number of sides of the base, the expression for the number of faces of the pyramid is given by
number of faces = n + 1.
Should be 51.26 if you did 205.04 and divided it by 4
